All your sail trim on one screen
Made for cruising skippers with a main and genoa, for anyone learning to sail, and for anyone who sails with friends and wants to do it better.
Wind rose
Drag the gold circle to where you feel the wind and see your point of sail (close-hauled, close reach, beam reach, broad reach or running) and your tack.
Main and genoa
Sheet, traveller, vang, outhaul, cunningham, backstay, lead car and halyard: how to set each one on that point of sail, step by step.
Telltales
What it means when the windward or leeward telltale flutters, and what to adjust to fix it.
Reefing for your boat
How many reefs to take and how much genoa to furl for the wind strength, your boat length and your point of sail.
Heading and forecast wind
Enter your heading and the forecast wind direction and the app works out the angle for you, so you can plan the passage before you leave.

No signal needed, no permissions requested and no data collected. In English, Spanish and French.
